LOS tags never had any build configuration data so there is little incentive to mess with them. The VIN is in line with the body date & schedule info of 09D, A381.

I believe the tag may have been off the car as the paint on it seems to differ from the area around it. It also appears there is paint under it. In production the tag was attached long before any painting was done.

I would not be concerned about it. However look inside the trunk at the area around the hinges to ensure the car was always orange.

After looking at thousands of tags over the last 35 years it is easy to determine when one has been removed. But that is more due to careless re-installation than my experience. Someone who knows what they are doing could indetectably r & r a tag.
